Hello Carl,
Are you taking the images for each chunk using the rigid camera rig?
If so, then I would rather suggest to use 4D processing approach (multi-frame chunk).
Another option is to export the cameras after alignment from the reference chunk (File Menu -> Export Cameras) to XML format and use Import Cameras option + Built Points command to perform the image matching in the new chunks, preserving the exterior and interior camera orientation from the reference chunk.
